Early this afternoon I tested 5 times using my new Accu-chek Nano trying to get a handle on my blood sugar. I got these results

156 (higher than I expected)
121 (different enough that I wanted to reconfirm)
161 (OK - the higher # is probably right but to confirm..)
129 (sigh)
134

I know these are all 20% plus or minus something like 137 and I used 140 to correct but I never had such a repeated spread using FreeStyle. Do Accu-Chek users regularly have to deal with this level of variance?

Thanks,

Maurie

So let me present some research on this question. A study reported in April of this year looked at 5 meters and compared their accuracy, the Accucheck Aviva, essentially the same as the Nano came out well. An earlier examination in 2010 found that 40% of 27 meters failed to meet the ISO 15197 standard, but all the Accucheck meters met the standard. The standard itself is pretty loose, allowing 5% of readings to be totally "trash" and only requires that 95% of readings be within accuracy bounds.

Bernstein has recommended the Accucheck Aviva for some time.

I continue to answer despite being an avowed onetouch users. I can claim that is ok, cause I actually have an Aviva, but it is not a preferred brand with my insurance.

Thanks - I didn't realize that 1 out of 20 readings can be total trash. That's one every two days for many/most of us.
